•DO allow sufficient time for the thermometer to stabilize before making
measurements. This allows for the best accuracy.
•DO use the correct drive current with the thermometer to prevent error
in temperature or resistance. Hart Scientific recommends 1mA.
•DO anneal the thermometer at 600 to 661°C for 12 hours if it becomes
oxidized.
•DO use the protective shipping box or case provided or other protec-
tion when the thermometer is not in use.
•DO NOTsubject the thermometer to any physical shock or vibration.
•DO NOTuse pliers or other devices to squeeze the sheath. This action
can permanently damage the PRT.
•DO NOTsubject the thermometer to temperatures above the highest
specified operating temperature.
•DO NOTexpose the thermometer’s handle or cables to extreme tem-
peratures. The temperature limits of the handle are: 0°C to 80°C
•DO NOTsubmerge the handle or cable in liquids.
•DO NOTscrew a clamp down so tight that it dents the sheath. This can
permanently damage the PRT.
